17.5-inch Tall Radiator for LS and LT Engine Swaps in 1964-1967 Pontiac GTO A-Body
Whether you are fitting an LS or LT motor into your classic GTO manual trans setup, choosing the right radiator is key to preserving engine bay appearance and maintaining factory coolant routing. The 1964 through 1967 GTO Radiator 17.5" tall for manual trans swaps holds the original core height to match brackets, shrouds, and hose connections without any trimming. Built from corrosion resistant aluminum with precision port placement, it keeps coolant moving during highway runs or city traffic while dropping into the A Body frame as a direct replacement. It ships ready for DIY installers and meets strict dimensional standards for a reliable install every time.
Precise 17.5 inch Core Height Integration
The 17.5 inch core height matches the original radiator dimensions for 1964 through 1967 Pontiac GTO A Body frames without any trimming. This ensures that factory hose connections, shroud mounts and bracket locations remain unchanged when installing an LS or LT engine with a manual transmission. With precision port placement, coolant routing follows the factory path to avoid hose kinks and maintain efficient flow under varied driving conditions. By aligning with the stock layout, the radiator preserves the classic underhood look while eliminating the need for custom fabrication. Enthusiasts gain a seamless upgrade that respects the car's original design intent.
Aluminum Construction for Rapid Heat Transfer
Constructed from high quality aluminum, this radiator offers exceptional thermal conductivity to handle the heat output of LS and LT powerplants in a vintage chassis. Aluminum's natural ability to dissipate heat quickly reduces coolant temperatures during spirited driving or city traffic, helping to prevent engine heat soak that can diminish output. The low weight of the material also contributes to overall mass reduction, enhancing handling response in a restored GTO. Corrosion resistance further extends service intervals by protecting internal passages from rust in high temperature conditions. This balance of lightness and durability supports both daily use and occasional track events.
Finish Options for Corrosion Protection and Style
Choose between a natural bare aluminum appearance that highlights weld details and machining marks or a black epoxy coating for added resistance against moisture, road salt and debris. The epoxy finish forms a resilient barrier on tanks and fins while preserving heat rejection characteristics, as the underlying core design remains unchanged. Bare aluminum offers a period correct look that complements classic restoration projects, while the epoxy option suits restomod builds seeking a modern aesthetic. Both finishes deliver consistent performance and long term protection so builders can select the style that best fits their vision. Installation procedures remain identical regardless of finish choice.
Manufactured in the United States for Direct Fit Reliability
This radiator is built in the United States to strict dimensional standards, ensuring each unit fits the A Body frame of 1964 to 1967 Pontiac GTO without adjustment. Precision welding and quality assurance processes deliver consistent core height and port alignment, so installers experience a straightforward, drop in fit every time. Ready for DIY enthusiasts or professional shops, the radiator ships fully assembled and conforms to factory mounting points for manual transmission applications with no need for special tools. The locally produced design also bolsters resale value through documented craftsmanship and proven compatibility.
